Summary
Both agents can lengthen the QTc interval, so concurrent use increases the likelihood of torsade de pointes. The risk is amplified by electrolyte abnormalities or cardiac disease.
What this interaction means in plain words
Chlorpromazine and Givinostat can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Chlorpromazine belongs to Central Nervous System; Givinostat belongs to Miscellaneous.
Why it happens
Additive QT prolongation through effects on cardiac repolarization.
What to do
Avoid if possible. If coadministration is necessary, obtain ECGs at initiation and during use, and withhold givinostat if QTc exceeds 500 ms or rises markedly from baseline.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
